John Herschel discovered NGC 6753 = h3779 on 5 Jul 1836 and logged "pB; R; gbM; 80"." His position is accurate.

According to Sandage (1975), this galaxy is a member of the NGC 6769 group. Members include NGC 6739, NGC 6769, NGC 6770, NGC 6771, NGC 6782, IC 4827, IC 4831, IC 4842 & IC 4845. Possible additional members include NGC 6753, NGC 6758, NGC 6780, NGC 6776, IC 4837, IC 4839 & IC 4889.

200/250mm - 11" (8/8/04 - Haleakala Crater): moderately bright and large at 127x, round, 1.2' diameter, fairly well-concentrated to a small bright core. A mag 12 star is off the SE edge of the halo and a mag 13 star is off the SW side (1.3' from center). Located 3.2' S of mag 10 HD 178302. Viewed at ~12 degrees elevation. Brightest in a group including NGC 6758 and NGC 6780.

600/800mm - 30" (10/12/15 - OzSky): at 394x; very bright, large, slightly elongated N-S, ~2.2'x1.8', fairly sharply concentrated with an intense elongated core that gradually increases to the center. A mag 12 star is at the southeast edge, 1.0' from center and a fainter star is off the southwest side. ESO 184-025 lies 6' SE and IC 4826 is 12' SE. ESO 184-025 appeared fairly faint, fairly small, thin edge-on 5:1 WSW-ENE, 0.7'x0.15', near the midpoint of NGC 6753 6' NW and IC 4826 6' SE.
